Answer:

Option C & D

Step-by-step explanation:

<u>__________________________________________________________</u>

<u>FACTS TO KNOW BEFORE SOLVING</u> :-

Lets say there's an expression x^{\frac{a}{b} } .

It can be also written it as → (\sqrt[b]{x} )^{a} and vice-versa.

<u>__________________________________________________________</u>

Lets come to the question.

  • In option A , 7^{\frac{5}{7} } can be also written as (\sqrt[7]{7} )^{5} . But it doesn't match with the other expression given. Hence they are not equivalent expressions.
  • In option B , 6^{\frac{2}{7} } can be also written as (\sqrt[7]{6} )^{2} . But it doesn't match with the other expression given. Hence they are not equivalent expressions.
  • In option C , 5^{\frac{3}{2} } can be also written as (\sqrt{5} )^{3}. Hence they are equivalent expressions.
  • In option D , (\sqrt[4]{81} )^{5} can be also written as 81^{\frac{5}{4} } . Hence they are equivalent expressions

Thus , Option C & D are correct.

xxTIMURxx [149]

Answer:

to make a unit rate using a table you would take an input/output from a table and convert it into a fraction. Then you would take that fraction and simplify it. Sometimes you might have to choose a new input/output in order to make the simplification easier.

Example-

2:4

4:8

6:12

8:16

        Turn one into a fraction
